What is the composition of the liquid used for discharge cells that are not used anymore in the process ?
@whyyes183 Жыл бұрын
please don't overcrowd the workspace, cap facing downward, gloves with long sleeves, ethanol spraying your hands with gloves, when moving in and out of the chamber, not speaking while doing work or wear a mask for added protection, have the discard station separate from the other stuff, and clean it well with ethanol and turn on the UV light after completion of use. That's all I remember.

Cap facing downwards only apply to bsc class 1. In class 2 bsc, only filtered air can pass through down from above, so that’s why they mentioned to not go over the cap earlier in the video. Facing it downwards may expose the inside to the contaminants on the surface.

so many bad practices here. so many things enter the BSC without being sprayed with EtOH, splashing detergent that eats cell walls. exposed skin, blocked air flow, sticking the micropipette directly into a source container. basically just do the exact opposite of what this lady did and you will be fine
@Defosaur5 жыл бұрын
isn't it safer to aliquot portions of media and such in 50 ml tubes, instead of sticking the whole micropippete into the liter bottle? that's the way I do it.

4:18 "I multiply by 10 to the 4, meaning I'm converting my uL to mL". Wait, I'm confused. There are 1000uL in 1mL, so to get from uL to mL you would multiply by 1000, which is 10 to the 3, not 10 to the 4.

2 obvious mistakes in this video. 1. overcrowded workspace that is blocking airflow through the cabinet and especially the tubes of media would have no airflow protecting them where they are. 2. there is a gap between gown and glove which leaves open to higher risk of contamination. gloves should always go over the cuff.
@funny1174410 ай бұрын
A general question regarding contamination: Is it a routine to spray alcohol absolutely on every object that is inserted in the laminar flow cabinet. But how about the flasks that are transported to the microscope for checking stem cell detaching ? I did not see in any video on KZbin such an operation of spraying the flask before reintroducing it in the laminar flow cabinet !
@jackistripping3 ай бұрын
in theory sure..in any real lab? Rarely. The entire area is already decontaminated, and most labs don’t deal with level 3 pathogens that require full ppe anyway. It could use more airflow though, but not really an issue

Blocking the laminar flow intake vents...this is a class II biosaftey cabinet. It protects the cells from contamination not the user

The thing is that if your using sterile gloves there shouldn't be a contamination problem from the hands. Why she's not using sterile gloves to begin with is beyond me, as it would seem like sterile gloving using a closed-glove technique would avoid about 75 percent of the potential problems.
@sageartchannel33635 жыл бұрын
Not many labs have sterile gloves, this is easier or cheaper. but no matter what you are using the should be followed as at some point the gloves can be contaminated so better to teach new starters this way.
@iangraham8717 жыл бұрын
The amount of overcrowding in the biosafety cabinet shown here will have a serious impact on its effectiveness both in keeping a sterile environment and protecting the user (if using infectious materials). Really poor practice!

@science_mbg7 жыл бұрын
If it is not too much contaminated then I can disinfect and use but if I am not sure I definitly change it. Because I cannot risk it for just pair of gloves

the cap should be downward, media can be kept at centralback, too much of equipment and reagents not sure if all are really needed. Then the discard bin should be outside (except whatt I saw is a sterile pippette).

@conorphillips67339 жыл бұрын
And I thought you were supposed to put the cap down right way up instead of upside down. Then if something passes over such as your hand there's less of a chance that contamination will occur.
@lovelyperson97 жыл бұрын
I've heard there's ongoing debate whether to place caps right-side up or upside down. Each side of the argument has its appealing reasons, I suppose.

Really great video except for the initial mixing of cells. That's not effective. In order to attain an even distribution of cells in that suspension, it would be essential to mix using a P1000 at the very least. This is important because otherwise your cell count is gonna be way off.
